Returns members in a sorted set within a lexicographical range in reverse order.
ZREVRANGEBYLEX key
max min [LIMIT
offset count]
When all the elements in a sorted set are inserted with the same
score, in order to force lexicographical ordering, this command returns
all the elements in the sorted set at key with a value
between max and min.
Apart from the reversed ordering, ZREVRANGEBYLEX is
similar to ZRANGEBYLEX.
Array reply: a list of the members in the specified score range.
O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements being returned. If M is constant (e.g. always asking for the first 10 elements with LIMIT), you can consider it O(log(N)).
